God, 2
God's Self-Revelation to the Patriarchs
The Old Testament does not present a systematic doctrine of God but rather a living portrait that unfolds across centuries. The story begins with creation, where God is introduced as the sovereign Creator who brings all things into existence by His word (Genesis 1:1-3). This God is personal, purposeful, and relational — He creates humanity in His own image and enters into covenant relationship with them (Genesis 1:26-27).
God revealed Himself to the patriarchs — Abraham, Isaac, and Jacob — as the God who makes and keeps promises. To Abraham, He pledged descendants, land, and blessing for all nations (Genesis 12:1-3; 15:1-6). He identified Himself as "God Almighty" (El Shaddai, Genesis 17:1) and demonstrated His faithfulness through the miraculous birth of Isaac and the provision of a ram in place of Abraham's son on Mount Moriah (Genesis 22:1-14). The patriarchal God was not an abstract principle but a personal presence who appeared, spoke, covenanted, and guided.
The Mosaic Revelation: God as Yahweh
The pivotal moment in Old Testament theology came at the burning bush, where God revealed His personal name to Moses: "I AM WHO I AM" (Exodus 3:14). The name Yahweh (often rendered "the LORD" in English translations) expressed God's self-existent, eternal, and dynamic nature. He is not a static being but the living God who acts in history.
Through the Exodus, God demonstrated His character in action. He revealed Himself as the redeemer of the oppressed (Exodus 6:6-7), the sovereign over all other gods and powers (Exodus 12:12), and the holy lawgiver who established a covenant with His people at Sinai (Exodus 19-24). The Ten Commandments opened with the foundational declaration: "I am the Lord your God, who brought you out of the land of Egypt, out of the house of slavery. You shall have no other gods before me" (Exodus 20:2-3).
God's self-description to Moses on Sinai became the defining creedal statement of Old Testament faith: "The Lord, the Lord, a God merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness, keeping steadfast love for thousands, forgiving iniquity and transgression and sin, but who will by no means clear the guilty" (Exodus 34:6-7). This tension between mercy and justice runs through the entire Old Testament.
The Prophetic Period: Ethical Monotheism
The great writing prophets of the eighth through sixth centuries BC brought Israel's understanding of God to new depths. In a world of competing religious claims — where Baal worship threatened to corrupt Yahweh worship (1 Kings 18:21) — the prophets proclaimed that Yahweh alone is God, and that His primary demand is not ritual but righteousness.
Amos declared that God requires justice and righteousness rather than empty religious festivals (Amos 5:21-24). Hosea revealed the heartbreaking love of God for His unfaithful people, portraying the divine-human relationship through the metaphor of a faithful husband and an adulterous wife (Hosea 11:1-9). Isaiah's vision of God "high and lifted up" (Isaiah 6:1-8) combined transcendent holiness with personal commissioning. Micah distilled the prophetic message into a single sentence: "He has told you, O man, what is good; and what does the Lord require of you but to do justice, and to love kindness, and to walk humbly with your God?" (Micah 6:8).
Jeremiah brought the relationship between God and the individual to the forefront, promising a new covenant written on the heart (Jeremiah 31:31-34). Ezekiel emphasized God's transcendent glory while also affirming His concern for individual moral responsibility (Ezekiel 18:4, 30-32).
The Post-Exilic Period: Transcendence and Universalism
The Babylonian exile and its aftermath reshaped Israel's theology in significant ways. Contact with the wider world forced Israel to articulate more explicitly what had always been implicit: Yahweh is not merely Israel's national deity but the Creator and Lord of all nations and all history. The later chapters of Isaiah proclaim this with majestic force: "I am the Lord, and there is no other, besides me there is no God" (Isaiah 45:5).
During this period, a greater emphasis on God's transcendence developed. God became increasingly understood as exalted above the world, with angelic intermediaries (Daniel 10:13, 21) and divine wisdom (Proverbs 8:22-31) serving as bridges between the infinite God and finite creation. The synagogue tradition, which emerged during the exile, focused on the study of God's word as the primary means of knowing and worshiping Him.
Yet this growing sense of transcendence was balanced by an equally strong emphasis on God's immanence and care. The Psalms celebrate a God who is both enthroned in heaven and intimately present with each individual: "Where shall I go from your Spirit? Or where shall I flee from your presence?" (Psalm 139:7). God is both the cosmic king and the personal shepherd (Psalm 23:1).
Key Attributes of God in the Old Testament
Across all periods, certain attributes of God remain constant in the Old Testament. He is holy — utterly distinct from creation and from sin (Isaiah 6:3; Leviticus 19:2). He is righteous — His actions and demands are characterized by justice (Psalm 145:17; Deuteronomy 32:4). He is faithful — His covenant promises are reliable across generations (Deuteronomy 7:9; Lamentations 3:22-23). He is compassionate — moved by the suffering of His creatures (Psalm 103:13; Exodus 22:27). And He is sovereign — governing all nations and all history according to His purposes (Daniel 4:34-35; Isaiah 46:9-10).
These attributes are not abstract philosophical categories but qualities revealed through God's actions in history. The Old Testament knows God not primarily through theological speculation but through His deeds — creating, calling, delivering, judging, and redeeming His people.
Biblical Context
The Old Testament's revelation of God spans every book and genre. The Pentateuch establishes God as Creator, covenant-maker, and lawgiver. The historical books show God acting in Israel's national life. The Psalms express the full range of human response to God's character. The wisdom literature explores God's governance of the moral order. The prophetic books proclaim God's holiness, justice, mercy, and sovereign purposes. Key revelatory moments include the burning bush (Exodus 3), Sinai (Exodus 19-34), Elijah's contest with Baal (1 Kings 18), Isaiah's temple vision (Isaiah 6), and the restoration promises of the exilic prophets (Isaiah 40-55; Ezekiel 36-37).
Theological Significance
The Old Testament's progressive revelation of God lays the foundation for the New Testament's proclamation. The personal name Yahweh, the tension between holiness and mercy, the covenant pattern of divine initiative and human response, and the prophetic insistence on ethical monotheism all prepare for the incarnation of God in Christ. The Old Testament establishes that God is not a philosophical abstraction but a living Person who enters into relationship with His creatures, makes binding commitments, and faithfully pursues His redemptive purposes through history.
Historical Background
Israel's understanding of God developed in dialogue and conflict with the religions of surrounding cultures. The Canaanite religion centered on Baal and Asherah as fertility deities, and the prophets' polemic against Baal worship is well attested in both Scripture and archaeological sources (the Ugaritic texts from Ras Shamra illuminate the mythology behind Baal worship). Mesopotamian religions featured elaborate pantheons and creation myths (Enuma Elish, Atrahasis Epic) that share some structural parallels with but differ fundamentally from the Genesis accounts. The Elephantine Papyri, documents from a Jewish military colony in Egypt (fifth century BC), reveal the complexity of Jewish religious practice in the diaspora. The Dead Sea Scrolls demonstrate the rich diversity of theological reflection within Second Temple Judaism.
